内容摘要：We consider the inverse scattering problem by a locally rough surface with phaseless near-field data. A uniqueness result is obtained for the inverse problem. Further, a direct imaging method is proposed to reconstruct the locally rough surface from the phaseless near-field data. Finally, numerical experiments are carried out to demonstrate the effectiveness of our imaging algorithm.
